One of the main challenges in skull base tumor removal is the thermal damages that occur in response to grinding the skull bone. During this process, temperature rise occurs at the site of bone grinding, and may cause irreversible thermal damage to the bone, nerves, and arteries. The aim of the present research is to study temperature changes during high-speed grinding of bone via infrared thermography to determine the threshold of high-speed cutting range (HSC-range) in order to achieve the minimum temperature rise and minimize the resulting thermal damages. Experimental tests have been performed in 75 states using the parameters of cutting speed (25 states) and feed rate (3 states) on bovine femur samples. The temperature changes of bone have been measured through infrared thermography. The results indicated that temperature rise had a direct relationship with the tool feed rate. Further, the cutting speed of 250 m.min-1 at different feed rates was the HSC-range threshold, after which a descending trend of temperature rise emerged; each led to the minimum temperature rise and beyond HSC-range, the temperature rise found an ascending trend. Thus, in order to reduce the thermal damage in neurosurgical bone grinding, the following parameters are suggested as follows: cutting speed 350-425 m.min-1 for the feed rate 20 mm.min-1 (ΔT= 4.8-8.5°C ); cutting speed 500-550 m.min-1 for the feed rate 30 mm.min-1 (ΔT= 7.2-9.3°C), and cutting speed 650-675 m.min-1 for the feed rate 40 mm.min-1 (ΔT= 10-12.5°C).
